changing focus

You should try this

  ShowWindow(Wnd: HWnd; CmdShow: Integer): Bool;

But you need to retrive to windows Hwnd handle to use it, if you know windows classname or windowname.

  FindWindow(Classname, WindowName: PChar): HWnd;

I use winsight to get the handle to the window and use the handle, The function returns success but the window is not bought to the forground..

SetForegroundWindow does work if you pass it the correct handle, but you can't get this handle from ShellExecuteEx, you need to use FindWindow or more likely EnumWindows.

Could you list the window classes and names for the app as reported by WinSight? If so, I'll write you some code.

1. use SetActiveWindow(handle of the window)
2. in order to find the handle of the window use
FindWindow(windowclass,nil)
3. in order to find the class of the window use the spy program.

SetActiveWindow will only bring the window to the forground if the window belongs to the application making the call. I am trying to activate a vindow from a different app.

Comment for Sperling:-

I would appreciate an example of EnumWindows callback. Essentially what i am trying to accomplish is to activate an application. If an instace of that application already exists then simply set the focus to the existing instance. Note that the application is a third party app such as netscape for example so i can not chech for previous instance from within the app. I will know befor hand wich apps i will want to run so i would have no problem making a comparison of the windows class.  If you can think of a better way of doing this I would be glad to hear it. for the purpose of this exercise (EnumWindows) feel free to use any windows class or you can use RegEdit_RegEdit.

thanks
